摘要

本論文以慢速浸拉方式將無皂乳液聚合之聚苯乙烯微球自組裝排列成緊密堆積的蛋白石(opal)光子晶體陣列，製作出可快速定性辨識甲醇與乙醇的晶片。當甲醇和乙醇分別滴入蛋白石晶片後，可由晶片的反射峰對應在色度圖上的移動路徑快速辨識二者。此外，為更進一步製作乙醇濃度定量分析晶片，我們將二氧化鈦溶膠滲入聚苯乙烯微球陣列縫隙後，於高溫燒結去除聚苯乙烯微球後獲得二氧化鈦反蛋白石(inverse opal)孔洞結構，並比較PS蛋白石結構及不同燒結溫度的TiO2反蛋白石結構對乙醇濃度的靈敏度。

Polystyrene (PS) microspheres were synthesized by emulsifier-free emulsion polymerization and then they were arranged as a close packed opal photonic crystals by a slow self-assembly dip-coating. The PS periodic microarray was applied as a rapid qualitative recognizable chip of methanol and ethanol in this study. Once we drop a dosage of methanol and ethanol into the PS opal chip respectively, we could distinguish both of them rapidly from the routes of the reflection positions of the chip in the chromaticity diagram. In addition, we made a quantitative identification chip for the concentration of ethanol in this study. A titania inverse opal structure was prepared by pouring titania gel into the voids of the PS microspheres array then sintering the PS/TiO2 template at high temperature. The sensitivity of the sintered TiO2 inverse opal structure for the concentration of ethanol was evaluated and investigated.
